Table 1.3 Warnings and cautionary statements

If it appears that the instrument is not working correctly, immediately contact Industrial Scientific.

Only qualified personnel should operate, maintain, and service the instrument.

Substitution of components may impair intrinsic safety, which may cause an unsafe condition.

Substituer des composants peut compromettre la sécurité intrinsèque, ce qui peut résulter en une situation
dangereuse.

Do not use in oxygen-enriched atmospheres. If the atmosphere becomes oxygen enriched, it may cause
inaccurate readings.

Oxygen-deficient atmospheres may cause inaccurate readings.

A rapid increase in a gas reading that is followed by a declining or erratic reading may indicate an over-range
condition, which may be hazardous.

Sudden changes in atmospheric pressure may cause temporary fluctuations in gas readings.

Temperatures below -20 °C (-4 °F) are likely to cause decreased functionality in the instrument's display screen
and man-down feature.

Sudden changes in ambient-air temperature will cause a form of sensor drift in the Carbon Monoxide/Hydrogen
Sulfide (CO/H2S) sensor (part number 17155306-J) that will produce temporary variations in the sensor's
readings:

 If the temperature suddenly increases, the CO reading will temporarily decrease and the H

2

S reading may

temporarily increase.

 CSA has assessed only the %LEL combustible gas detection portion of this instrument (the sensor part number 17155304-M only) for

Warnings and Cautionary Statements

Read and understand this Product Manual before operating or servicing the instrument. Failure to perform
certain procedures or note certain conditions—provided below and throughout the manual—may impair the
performance of the product, cause unsafe conditions, or both.

Table 1.3 Warnings and cautionary statements

 If the temperature suddenly decreases, the CO reading will temporarily increase and the H

2

S reading may

temporarily decrease.

The readings will stabilize when the sensor has acclimated to the change in temperature. For example, if the
ambient-air temperatures changes from a "room temperature" of 20 °C (68 °F) to an outdoor temperature of 0
°C (32 °F), the stabilization time is approximately 15 minutes; with smaller or larger changes in temperature,
stabilization time will be shorter or longer, respectively.

Note: If the sensor is to be zeroed after a sudden change in ambient-air temperature, allow the sensor and its
readings to stabilize before zeroing.

To avoid potentially inaccurate readings for some applications—monitoring for gases other than O2, CO, CO2,
H2S, and combustible gases [LEL/CH4]—only use a leather case as a carrying case. Do not power on, operate,
or power off the instrument while it is in a leather case.

Silicone and other known contaminants may damage the instrument’s combustible gas sensors, which can
cause inaccurate gas readings.

To support accurate readings, keep clean and unobstructed all filters, sensor ports, water barriers, and pump
intake port.

Charge the instrument’s battery only in nonhazardous locations using compatible accessories from Industrial
Scientific.

Chargez la batterie de l’instrument uniquement dans des lieux sans danger.

Perform all instrument service tasks and maintenance procedures in nonhazardous locations only. This
includes the removal, replacement, or adjustment of any part on or inside the instrument or its pump.

Exécutez toutes les procédures de service les tâches de service sur l’instrument uniquement dans des lieux
sans danger. Ceci comprend la dépose d’une pièce positionnée sur l’instrument ou à l’intérieur de celui-ci, ou
bien la rechange ou le réglage d’une telle pièce.

Battery contacts are exposed on battery packs when they are removed from the instrument. Do not touch the
battery contacts and do not stack battery packs on top of each other.

Do not use solvents or cleaning solutions on the instrument or its components.

Recommended Practices

Instrument Maintenance

The procedures defined below help to maintain instrument functionality and support operator safety.

Industrial Scientific minimum-frequency recommendations for these procedures are summarized below in
Table 1.4. These recommendations are provided to help support worker safety and are based on field data,
safe work procedures, industry best practices, and regulatory standards. Industrial Scientific is not
responsible for determining a company’s safety practices or establishing its safety policies, which may be
affected by the directives and recommendations of regulatory groups, environmental conditions, operating
conditions, instrument use patterns and exposure to gas, and other factors.

Settings

Settings control how an instrument will perform. They are used to help ensure the instrument is in
compliance with company safety policy and applicable regulations, laws, and guidelines as issued by
regulatory agencies and government or industry groups.

Utilities

Maintenance procedures are known as "utilities". Utilities are used to test the instrument or its components
for functionality or performance, or to clear an instrument's summary readings. Each utility is defined below.

Self-test.

The self-test is used to test the functionality of the instrument’s memory operations, battery, display screen,
and each alarm signal type (audible, visual, and vibration).

Bump Test (or "functional test").

Bump testing is a functional test in which an instrument's installed sensors are to be briefly exposed to (or
“bumped” by) calibration gases in concentrations that are greater than the sensors’ low-alarm setpoints.
This will cause the instrument to go into low alarm and will indicate which sensors pass or fail this basic test
for response to gas.

Zero.

Zeroing adjusts the sensors’ “baseline” readings, which become the points of comparison for subsequent
gas readings. During zeroing, the installed sensors are to be exposed to an air sample from a zero-grade­air cylinder or ambient air that is known—by the instrument user—to be clean air. The instrument makes no
judgement about the quality of the zero-air sample; its only task is to read that air sample as clean air.
Zeroing is also a prerequisite for calibration.

Settings

Before first use, when an installed sensor is replaced, and as needed.

Calibrationa

Before first use and monthly thereafter.

Bump testb

Before first use and prior to each day’s use thereafter.

Self-testc

As needed.

Calibration.

Regular calibrations promote the accurate measurement of gas concentration values. During calibration, an

instrument’s installed sensors are to be exposed to their set concentrations of calibration gases. Based on
the sensors’ responses, the instrument will self-adjust to compensate for declining sensor sensitivity, which
naturally occurs as the installed sensors are used or “consumed”.

Note: During calibration, the span reserve percentage value for each sensor is displayed. An indicator of a sensor's remaining
life, when the value is less than 50%, the sensor will no longer pass calibration

Summary Readings.

The time-weighted average (TWA), short-term exposure limit (STEL), and peak readings can each be
"cleared". When any summary reading is cleared, its value is reset to zero and its time-related setting is
also reset to zero.

a

Between regular calibrations, Industrial Scientific also recommends a calibration be performed immediately following each of these incidences:
the unit falls, is dropped, or experiences another significant impact; is exposed to water; fails a bump test; or has been exposed to an over­range (positive or negative) gas concentration. A calibration is also recommended after the installation of a new (or replacement) sensor.

b

When redundant sensors are operating on DualSense® technology, bump testing these sensors may be done less frequently based on
company safety policy.

c

The instrument performs a self-test during power on. For an instrument that is set for always-on, the instrument will automatically perform a
self-test every 24 hours. The self-test can also be completed on demand by the instrument user.

Note: The use of calibration gases not provided by Industrial Scientific may void product warranties and limit potential liability claims.

First Use

To prepare the Ventis Pro Series instrument for first use, qualified personnel should ensure the following
are completed:

 Charge the battery.
 Review instrument settings and adjust them as needed.
 Calibrate the instrument.
 Complete a bump test.

Wearing the Instrument

Based on the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) definition
of the breathing zone, it is recommended that the instrument be worn within a 25.4 cm (10") radius of the
nose and mouth. Refer to OSHA and to other agencies or groups as needed for additional information.

5

Remote Sampling

When sampling with the aspirated instrument, allow time for the air sample to reach the sensors and for the
sensors to respond to any gases that are present. Industrial Scientific recommends the allowance of two
minutes plus two seconds for each foot of sample tubing.

Cold-weather Operation

Use caution when operating the instrument in temperatures below -20 °C (-4 °F), which can diminish
display-screen legibility and man-down functionality. To help support functionality and available battery
power, the following practices are recommended.

 Do not operate the instrument in temperatures that are not within the temperature ranges of the

installed sensors (see "Table 2.5, Sensor specifications").

 Use a compatible, fully charged extended-run-time battery.
 Before using the instrument in the cold-weather environment, power it on a warm-up environment

(approximately 20 °C [68 °F]).

 Alternately operate the instrument in the cold-weather and warm-up environments.
 Do not operate the instrument unmanned.

Overview

The Ventis™ Pro Series portable gas monitors are used for personal protection to monitor for oxygen and a
variety of toxic gases and combustible gases.

Eleven compatible sensors are available for use with the Ventis™ Pro4 Multi-Gas Monitor, which can
provide readings for up to four gases. These sensors are among the 16 available for use with the Ventis™
Pro5 Multi-Gas Monitor, which can provide readings for up to five gases.

The instruments take gas readings every second and record readings-related data every ten seconds. Data
are stored in the instrument data log, which has these characteristics:

 Capacity for approximately three months of readings for a unit that is on 10 hours a day and has four

installed, operational sensors

 Data storage for up to 60 alarm events, 30 error events, and 250 manual calibrations and bump tests
 Downloadable using compatible accessories that are supported by iNet®, DSSAC, or Accessory

Software from Industrial Scientific.

Ventis™ Pro Series instruments use a multisensory alarm-warning-indicator system comprising audible,
visual, and vibration signals.

The instrument's display-screen language can be set for English, French, German, or Spanish.

Key Features

These communication-enhancing features support operator safety:

 Using iNet, DSSAC (Docking Station Software Admin Console), or Accessory Software, the safety

team can provide instrument operators with customized on-screen messages. The options include a
message that displays during the start-up sequence and those that display during gas events. A unique
instructional message can be set for each of these events for each sensor: gas present (alert, low
alarm, and high alarm), STEL, and TWA. the messaging options provide a total of 26 opportunities for
the safety team to communicate specific instructions to the instrument operator.

 The panic button provides instrument operators with the ability to turn on (and off) the instrument’s

high-level alarm. This can alert others who are nearby that the instrument operator is in distress,
someone else is in distress, or there is some concern about in-field circumstances.

 The man-down feature allows the instrument to sense when it has not moved. A man-down warning or

alarm may indicate the instrument operator is unable to move or press the panic button, or that the
instrument has become separated from its operator. Both the warning and alarm can be turned off by
the instrument operator.

 Gas information screens can be set for operation-mode access for the instrument operator who needs

to view setpoints for gas events and calibration gas concentrations.

Several features support safety in ways that encourage operator attention and understanding, or that aid in
the prevention of operator misuse, however unintentional.

 The full-screen alarm displays easy-to-read alarm details in “large type”.
 The gas-alert feature warns the instrument operator of the presence of gas in concentrations that may

be approaching the instrument’s alarm setpoints. Because it can be reset by the user, the alert also
serves as a form of acknowledgement, prompting the instrument operator to check the display screen
for gas readings and an instructional message, and to optionally turn off the alert.

 The alarm-latch feature is used to keep an alarm on after the alarm-causing condition no longer exists.

This serves to sustain alarm signals, which can encourage the instrument operator to check the display
screen for gas readings and an instructional message, and to optionally release the alarm latch.

 Programmed iAssign™ tags can be used by the instrument operator to assign an instrument to the

user-site data on his or her tag. This can help promote a sense of ownership among instrument
operators, encouraging their responsible use of the equipment.

 When used in combination with the security code feature, the instrument’s always-on option can help

prevent the instrument being powered off during operation.

 When the instrument is powered-off, the quick-status feature allows users to view this instrument

information: installed sensors, available battery power, and instrument serial number.

These hardware features help protect and reduce damage to the instrument:

 The raised ridge helps shield the sensor ports from dirt and damage when an instrument falls or is

dropped.

 The display screen is recessed to protect it from scratches and other damage.
 Rails help reduce wear from docking.

Compatibility

Sensors

Each instrument’s compatible sensors can be installed in one or more specific locations as depicted in

Figures 2.1 and 2.2 for Ventis Pro4 and Ventis Pro5, respectively. Table 2.1 provides the same information
but in list format, which is helpful for distinguishing among sensors of the same type. For example, there
are two H2S sensors that do not share installation locations or part numbers.
